NASA spots 54 potentially life-friendly planets

An orbiting NASA telescope is finding whole new worlds of possibilities in the search for alien life, spotting more than 50 potential planets that appear to be in the habitable zone.

In just a year of peering out at a small slice of the galaxy, the Kepler telescope has discovered 1,235 possible planets outside our solar system. Amazingly, 54 of them are seemingly in the zone that could be hospitable to life - that is, not too hot or too cold, Kepler chief scientist William Borucki said.

Until now, only two planets outside our solar system were even thought to be in the "Goldilocks zone." And both those discoveries are highly disputed.

Fifty-four possibilities is "an enormous amount, an inconceivable amount," Borucki said. "It's amazing to see this huge number because up to now, we've had zero."

The more than 1,200 newfound celestial bodies are not confirmed as planets yet, but Borucki estimates 80 percent of them will eventually be verified. At least one other astronomer believes Kepler could be 90 percent accurate.
